GEORGE WV. DOVER, OF CRANSTON, RHODE ISLAND.

SPECIFICATION forming part of Letters PatentNo. 711,152, dated October14, 1902.

Application filed May '7I 1902. Serial No. 106,320. (No model.)

To all whom. it may concern:

Be it known that I, GEORGE W. DOVER, a citizen of the United States,residing at Cranston, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Pins, ofwhich the following is a specification.

My invention relates to brooches and other pins adapted for securingfabrics, and has for its objects the ends commonly sought in this classof articles, including strength and cheapness of manufacture. Hithertothe joints or catches of these pins, or both, have been soldered to thepin-body. The soldering process has involved the expense of operatorsfor this purpose, as well as the cost of solder. Furthermore, thegreatest strain upon the parts of the pin are at the catch and joint,particularly the latter. Hence separation of the joint from the body isusual at this point.

My invention overcomes the evils above recited and attains the endsdesired by means of the structure hereinafter described, and illustrated.in the accompanying drawings, wherein- Figure l isa face view of ablank from which my improved pin is formed; Fig. 2, a similar view ofthe same with the walls of the joint partially bent; Fig. 3, a like viewwith the walls of the joint and the catch in final position; Fig. 4, atransverse section of the same on line x :r of Fig. 3, and Fig. 5 a sideelevation of the completed pin-body. Fig. 6 is a modified form of blank.

Like letters of reference indicate like parts throughout.

An embodiment of my invention is as follows: A blank A of any desiredshape and size is cut from a sheet of brass or other metal. by means ofcutters and dies. The blank has projecting from its side or end a lug B,consisting of two laterally-projecting ears a. Depending from these earsare projections b, which contact with the periphery of the pin-body A.Each of the ears a is pierced at c to form a bearing for the pivot d,upon which the pirrtongue 6 is to be mounted. The pin-body A is alsopierced by the original cutting with two openings f near the lug B insuch a position as to receive the projections b at a subsequent stage ofthe operation. Diametrically opposite the lug B, projecting from theblank A, is a pointed extension g. The blank cut as above described froma single piece of metal in one operation is next treated as follows: Thetwo cars a are bent upright, forming two parallel walls withinwardly-directed projections b, Fig. 2. The lug Bis next foldedinwardly until it assumes a position at right angles to the plane of themain body of the blank A, as shown in Figs. 3 and 5. In so doing theprojections 19 enter and traverse the openings f, above described,projecting slightly below the face of the blank A, Fig. 4. Theprojecting portions are riveted at b upon the face of the blank oppositethe joint, as shown in Fig. 5, thus permanently holding the completedjoint 13 in position. The extension 9 is bent upwardly and downwardly toform the catch.

I As suggested above, the pin-tongue e is mounted in the usual way upona pivot d, bearing in the openings 0 of the walls a of the joint. I

It will be observed that in the structure above described the use ofsolder is entirely dispensed with and that the required operations arefew, simple, and inexpensive.

It is obvious that when it is desired that a stone or other auxiliaryornament be superimposed upon the face of my pin-body the end may beattained without the use'of solder by cutting the original blank'A withperipheral prongsw. (Shown in Fig.6.) These prongs may be subsequentlybent over the edge of the auxiliary ornament to retain the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1. In a pin, the combination with thebody provided with perforations near its margin, of a joint integralwith the body, projections upon the under side of the joint andtraversing the perforations, and means for retaining 'the projections inplace.

2. In a pin the combination with the body provided with a perforationnear its margin of a joint integral with the body, a projection upon theunder side of the joint and traversing the perforation, and a head uponthe free end of the projection formed by riveting.

In testimony whereof I have affixed my signature in presence of twowitnesess.

GEORGE w. DOVER.
